HSI and HSV color space

Question

What is the difference between HSI and HSV color space? I want to use HSI color space but I did not find any useful material for HSI. Is HSI the same as HSV?

Answer 1

From the mathematical formula, the Hues are the same for HSV and HSI when you are trying to make the conversion from RGB to one of them.

Saturation in HSL is dependent on max, min, and Lightness, while HSV's Saturation is only max and min dependent. (max and min are the maximum and minimum pixel value among R, G, B space).

Value is max while the Lightness is (max + min)/2
